[Evolution of tuberculosis/HIV coinfection in Metropolitan Santiago, Chile from 2005 to 2018].

BACKGROUND

Tuberculosis (TB)/HIV coinfection has a high mortality rate.

AIM: To describe socio-epidemiological characteristics of tuberculosis (TB)-HIV coinfection, and aspects associated with its prevalence, from 2005 to 2018.

MATERIAL AND

METHODS

Analysis of the registry of the tuberculosis control and elimination program of three public health services of metropolitan Santiago. The variables considered were: TB/HIV coinfection, age, sex, location of tuberculosis, bacteriological confirmation, incarceration, commune of residence, country of origin and effectiveness of the tuberculosis therapy.

RESULTS

We analyzed 7507 TB cases, of whom 12% corresponded to cases of coinfection. The number of coinfections doubled in the last 6 years. In 2018, 45% of coinfection cases occurred in migrants. Of the total cases evaluated, 53% were successfully treated and 28% died.

CONCLUSIONS

The remarkable increase in TB/HIV coinfection, urgently demands new prevention and control strategies, aimed at the most vulnerable groups.
